PROBLEM TO BE SOLVED: To mainly and significantly shorten a start time for a vehicular head-up display device.SOLUTION: A vehicular head-up display device includes: an optical component 11 which guides an image 3 of a display device 2 to a reflection member 6 provided in front of a driver seat 4; and a movable device 14 which is capable of displacing the optical component 11 between a use position 12 and a standby position 13. The movable device 14 has a drive device 15 and a reduction gear mechanism 16 which displaces the optical component 11 by driving force of the drive device 15. The reduction gear mechanism 16 has a forcible movement region 31 for forcibly moving the optical component 11 by the driving force of the drive device 15 and a free movement region 32 where the optical component 11 can freely move regardless of the driving force of the drive device 15. In the free movement region 32, energization means 33 is provided to instantly displace the optical component 11 to the use position 12.SELECTED DRAWING: Figure 3C

    【課題】主に、車両用ヘッドアップディスプレイ装置の起動時間を大幅に短縮し得るようにする。【解決手段】表示装置2の画像3を運転席4の前方に設けた反射部材6へ導く光学部品11と、光学部品11を使用位置12と待機位置13との間で変位可能な可動装置14とを備え、可動装置14が、駆動装置15と、駆動装置15の駆動力によって光学部品11を変位する減速歯車機構16とを備えた車両用ヘッドアップディスプレイ装置に関する。減速歯車機構16が、駆動装置15の駆動力によって光学部品11を強制的に移動する強制移動領域31と、駆動装置15の駆動力によらずに光学部品11が自由に移動可能な自由移動領域32とを備える。自由移動領域32で、光学部品11を即座に使用位置12へと変位させる付勢手段33を設ける。【選択図】図3C
